apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: http-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: http-source
    properties:
      url: "https://gist.githubusercontent.com/nicolaferraro/e3c72ace3c751f9f88273896611ce5fe/raw/3b6f54060bacb56b6719b7386a4645cb59ad6cc1/quote.json"
  sink:

Make sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the http-source-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the source using the following command:

kubectl apply -f http-source-binding.yaml
